NEWS RELEASE

Clinical Trial of New Cardiovascular Patch LaunchedTokyo, Japan, June 26, 2019--- Osaka Medical College, Fukui Tateami Co., Ltd. andTeijin Limited announced today that the alliance has launched a clinical trial of their
newly developed patch material, OFT-G1 (provisional name), for cardiovascular surgery
and the first surgery using the OFT-G1 was successfully performed.
The OFT-G1 is revolutionary designed by surgical expertise in cardiovascular surgery ofOsaka Medical College, pioneering warp-knitting technology of Fukui Tateami, andadvanced polymer-application technology of Teijin. The joint development of theOFT-G1 has been supported by a special program designed to facilitate collaborations
between medical academia and industrial field promoted by the Japan Agency for
Medical Research and Development (AMED). The Japan Ministry of Health, Labor andWelfare has designated the OFT-G1 as a SAKIGAKE product, which afford the OFT-G1
various incentives to speed up the approval process for clinical use.
Many kinds of cardiovascular patches have been widely used for surgical corrections,such as closure of defects in the hearts and enlargement of narrow vessels. However,previous products have many drawbacks and often cause reoperation in the long term.
While the OFT-G1 reveals its strong and elastic structure as the previous products, theOFT is the only product in which the absorbable portion is naturally replaced with thepatients’ own tissue after implantation. This is why the OFT-G1 is ideal for
cardiovascular surgery especially in children who need the implanted material could
expand in size along with their body growth. Therefore, the OFT-G1 is expected to avoid
reoperation causing physical, mental, and economic burdens on patients and theirfamilies.
The first surgical implantation of the OFT-G1 in human was performed on 4-month-old
infant who needed a patch closure of a large ventricular septal defect. The patient
recovered and discharged from hospital uneventfully and currently receives outpatient
follow-up.
Osaka Medical College, Fukui Tateami, and Teijin are continuing the clinical trial toprove the clinical effectiveness and safety of the OFT-G1, an approved cardiovascular
patch as quickly as possible in Japan followed by other countries worldwide. They will
also continue any efforts in expanding product development to contribute bright future
for patients with cardiovascular diseases.
